dont orget you need customized ($120 or so if you make your own) axles if this is going into a civic. and as far as the radiator fan i bought mine at autozone, just asked for an electric fan for my radiator and looked at a few then chose one. Also throw in $20-50 for an injector resistor pack if you dont have one already.
If you dont have suspension upgrades your front end is gonna bounce quite a bit too.
usually when doing a swap with au sed engine its a good idea to put in a new clutch new timing belt, new water pump new thermostat and a few other things that are easier to replace with then engine out, every swap i have bought has had a worn clutch...
